Nemesia plant named ‘Pencand’

ABSTRACT

A new and distinct cultivar of Nemesia plant named ‘Pencand’ that is characterized by a trailing, compact, mounding habit, dense upright spikes of fragrant white to pink flowers with yellow centers, and light green leaves. In combination these characteristics set ‘Pencand’ apart from all other existing varieties of Nemesia known to the inventor.

Genus/species: Nemesia hybrid.

Denomination: ‘Pencand’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesiaplant known botanically as Nemesia hybrid and that will be referred tohereinafter by the cultivar name ‘Pencand’.

The new Nemesia is a product of a planned breeding program conducted bythe Inventor in Netherwent, Wales. The breeding program objectives wereto improve upon well-known varieties such as Nemesia denticulata‘Confetti’ (unpatented), Nemesia caerulea ‘Innocence’ (unpatented),Nemesia caerulea ‘Joan Wilder’ (unpatented), Nemesia caerulea ‘Woodcote’(unpatented), and Nemesia caerulea ‘Elliott's’ (unpatented). The goalsof the breeding program were to improve on plant habit by breedingplants that were more compact, with stiff, upright flower spikes,increase the size of the flower and the length of flowering time,improve the color range by producing clear colors, and produce plantsthat root readily and consistently from vegetative stem cuttings.

The new Nemesia originated from a cross-pollination made by the Inventorin 1996 of an unnamed and unpatented Nemesia hybrid, as the female, orseed, parent with an unnamed and unpatented Nemesia hybrid, as the male,or pollen, parent. The cultivar ‘Pencand’ was discovered and selected bythe Inventor as a plant within the progeny from this cross-pollinationin a controlled environment in Netherwent, Wales, in 1996.

‘Pencand’ is distinguishable from the parent plants by white to pinkflowers with yellow center, a trailing, compact, mounding habit, anddense, upright fragrant flower spikes. The leaves are lanceolate inshape and exhibit thicker tissue than other Nemesia known to theinventor.

‘Pencand’ was first asexually propagated by the Inventor in 1997 in acultivated area or Netherwent, Wales using vegetative stem cuttings andhas shown that the unique features of this new Nemesia plant are stableand reproduced true to type in successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thedistinguishing characteristics of ‘Pencand’. In combinaton these traitsset the new cultivar apart from all other existing varieties of Nemesiaknown to the inventor. ‘Pencand’ has not been tested under all possibleconditions and phenotypic differences may be observed with variations inenvironmental, climatic, and cultural conditions, however, without anyvariance in genotype.

1. Nemesia ‘Pencand’ exhibits a trailing, mounding and compact habit.

2. Each individual plant of Nemesia ‘Pencand’ exhibits fragrant flowersthat are white to pink in color with yellow centers.

3. Nemesia ‘Pencand’ exhibits dense upright flower spikes.

4. Nemesia ‘Pencand’ is floriferous and exhibits large, repeat-floweringheads.

5. Nemesia ‘Pencand’ is hardy to minus 5° Centigrade.

6. Nemesia ‘Pencand’ can be used in beds, borders and window boxes.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of thenew Nemesia cultivar ‘Pencand’ showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the drawings may differ from the color values cited in thedetailed botanical description which accurately describe the actualcolors of the new variety ‘Pencand’. The plants are 4-months-old, in10-centimeter containers and were grown under greenhouse conditions inSan Diego, Calif.

The drawing on sheet 1 illustrates the entire plant's, habit and flowersfrom a side perspective.

The drawing on sheet 2 is a close-up view of the flower. The drawingswere made using conventional photographic techniques. Although colorsmay appear different from actual colors due to light reflectance, theyare as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Nemesia plant named‘Pencand’. Data was collected in Arroyo Grande, Calif. from 4-month-oldplants grown in 10-centimeter containers under greenhouse conditions.Phenotypic differences may be observed with variations in environmental,climatic, and cultural conditions. The color determinations are inaccordance with The 2001 Royal Horticultural Society Colour Chart exceptwhere general color terms of ordinary dictionary significance are used.The growing requirements are similar to other Nemesia plants.
